Patch set updated for coreboot: RISCV: Clean up the common architectural code
by Ronald G. Minnich 23 Oct '16

23 Oct '16

Ronald G. Minnich (rminnich(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/17058 -gerrit commit ced48c0300b446ad2c6301e2f1fa3a913098415d Author: Ronald G. Minnich <rminnich(a)gmail.com> Date: Wed Oct 19 08:07:13 2016 -0700 RISCV: Clean up the common architectural code This version of coreboot successfully starts a Harvey (Plan 9) kernel as a payload, entering main() with no supporting assembly code for startup. The Harvey port is not complete so it just panics but ... it gets started. We provide a standard payload function that takes a pointer argument and makes the jump from machine to supervisor mode; the days of kernels running in machine mode are over. We do some small tweaks to the virtual memory code. We temporarily disable two functions that won't work on some targets as register numbers changed between 1.7 and 1.9. Once lowrisc catches up we'll reenable them. We add the PAGETABLES to the memlayout.ld and use _pagetables in the virtual memory setup code. We now use the _stack and _estack from memlayout so we know where things are. As time goes on maybe we can kill all the magic numbers.

Patch set updated for coreboot: RISCV: Clean up the common architectural code
by Ronald G. Minnich 23 Oct '16

23 Oct '16

Ronald G. Minnich (rminnich(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/17058 -gerrit commit b386fcd90c0b895fa41ebeac7eaac1a52be9e945 Author: Ronald G. Minnich <rminnich(a)gmail.com> Date: Wed Oct 19 08:07:13 2016 -0700 RISCV: Clean up the common architectural code We provide a standard payload that makes the jump from machine to supervisor mode; the days of kernels running in machine mode are over. We do some small tweaks to the virtual memory code. We temporarily disable two functions that won't work on some targets as register numbers changed between 1.7 and 1.9. Once lowrisc catches up we'll reenable them. We add the PAGETABLES to the memlayout.ld and use _pagetables in the virtual memory setup code. We now use the _stack and _estack from memlayout so we know where things are. As time goes on maybe we can kill all the magic numbers.

Arthur Heymans (arthur(a)aheymans.xyz) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/17033 -gerrit commit e3690a2258c77eb43576b80dc54eb8ab8d01d298 Author: Arthur Heymans <arthur(a)aheymans.xyz> Date: Sat Oct 15 18:00:22 2016 +0200 mb/gigabyte/ga-945gcm-s2l: add mainboard Startpoint was Intel d945gclf. Resume from suspend does not seem to work. It requires to reset the Realtek nic, which currently hardcodes the MAC address. P-states don't seem to work or are not used by linux even though SSDT is being generated. (Same may hold for C-states) Everything else seems to work fine.

Patch set updated for coreboot: mb/gigabyte/ga-945gcm-s2l: add mainboard
by Arthur Heymans 22 Oct '16

22 Oct '16

Arthur Heymans (arthur(a)aheymans.xyz) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/17033 -gerrit commit dd4c2c483fa091b2dc1c5a58f7ae3aeafff0a2d9 Author: Arthur Heymans <arthur(a)aheymans.xyz> Date: Sat Oct 15 18:00:22 2016 +0200 mb/gigabyte/ga-945gcm-s2l: add mainboard Startpoint was Intel d945gclf. Resume from suspend does not seem to work. It requires to reset the Realtek nic, which currently hardcodes the MAC address. Everything else seems to work fine.
